Detailed explanation-1: -The primary consumers are herbivores (vegetarians). The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. The secondary consumers tend to be larger and fewer in number. This continues on, all the way up to the top of the food chain.
Detailed explanation-2: -A first-level consumer in the food chain is a herbivore that eats producers (plants), and a second-level consumer is a carnivore that eats the first-level herbivore animals. So, an organism that is both first-level and second-level consumer is an omnivore.
Detailed explanation-3: -The difference between the primary consumers and secondary consumers is that the primary consumers are herbivorous, while secondary consumers are carnivorous or omnivorous. Carnivores feed on meat, while herbivores feed on primary producers, such as plants (autotrophs).
Detailed explanation-4: -Primary consumers that feed on many kinds of plants are called generalists. Secondary consumers are carnivores that prey on herbivorous animals. Omnivores, which feed on both plants and animals, can be considered as being both primary and secondary consumers.
